While I agree this looks like they're pulling out all of the stops, I think I might be a bit disappointed at the setting. The West was super popular back in the early 70s when the original debuted, but much less so these days. I wish they'd chosen a setting that is more popular. Perhaps Medieval World, given the popularity of GoT. Or some kind of Futureworld.
I suppose it could be argued "The West hasn't been done in a while!" And doing The West is probably cheaper than other options, like the Future. Still I can't help feeling like this was a missed opportunity. Roaring20s World would have been awesome.
I'm not that familiar with the material, but is it possible that they could switch worlds? Maybe that would be too gimmicky.
